Iterative reconstruction of high-dimensional Gaussian Graphical Models based on a new method to estimate partial correlations under constraints. [PDF]

, 2012
In the context of Gaussian Graphical Models (GGMs) with high-dimensional small sample data, we present a simple procedure, called PACOSE - standing for PArtial COrrelation SElection - to estimate partial correlations under the constraint that some of ...

Relationships between PCA and PLS-regression

Chemometrics and Intelligent Laboratory Systems, 2014
Abstract This work aims at comparing several features of Principal Component Analysis (PCA) and Partial Least Squares Regression (PLSR), as techniques typically utilized for modeling, output prediction, and monitoring of multivariate processes. First, geometric properties of the decomposition induced by PLSR are described in relation to the PCA of ...

Interpretable Machine Learning for Solvent‐Dependent Carrier Mobility in Solution‐Processed Organic Thin Films

Advanced Intelligent Discovery, EarlyView.
This work establishes a correlation between solvent properties and the charge transport performance of solution‐processed organic thin films through interpretable machine learning. Strong dispersion interactions (δD), moderate hydrogen bonding (δH), closely matching and compatible with the solute (quadruple thiophene), and a small molar volume (MolVol)

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

The EVA spectral descriptor [PDF]

, 2000
The EVA descriptor is derived from fundamental IR- and Raman range molecular vibrational frequencies. EVA is sensitive to 3D structure but has an advantage over field-based 3D-QSAR methods inasmuch as it is invariant to both translation and rotation of ...

A 3D-QSAR Analysis of CDK2 Inhibitors Using FMO Calculations and PLS Regression.

Chemical and pharmaceutical bulletin, 2019
We report a three-dimensional quantitative structure-activity relationship (3D-QSAR) analysis of CDK2 inhibitors using fragment molecular orbital (FMO) calculations and partial least squares (PLS) regression. In our analysis, fragment binding energies of

Extent of Sinus Surgery Is Associated With Disease Control in Biologic Treated Type 2 Dominant CRS

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background A greater benefit of biologics is observed after surgery in Type 2 chronic rhinosinusitis with nasal polyps (CRSwNP). However, the extent of surgery remains undefined in many studies. This study evaluated the extent of surgery on disease control in patients receiving biologics for refractory Type 2 dominant CRSwNP.

Robust Nonlinear Partial Least Squares Regression Using the BACON Algorithm

Journal of Applied Mathematics, 2018
Partial least squares regression (PLS regression) is used as an alternative for ordinary least squares regression in the presence of multicollinearity. This occurrence is common in chemical engineering problems.

Single-index Extreme-PLS regression

, 2021
L'objectif de cette communication est de proposer une nouvelle approche, appelée Single-index Extreme-PLS, pour la réduction de dimension en régression qui soit adaptée aux queues de distributions. Nous nous intéressonsà la combinaison linéaire des prédicteurs qui explique au mieux les valeurs extrêmes de la variable réponse dans un contexte de ...

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

The Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.
